INTEGRATED-OPTICAL LIGHT BEAM DIVIDER (MODIFICATIONS) Russian patent published in 2002 - IPC

FIELD: integrated optics and may be one of the elements of an optical 3-D integrated circuit with three-dimensional optical communications. SUBSTANCE: installed in the device in parallel with one of the sides of the wave-guide is a mirror movable relative to the plane of the waveguide, coupled with a source of mechanical displacements. The device has a number of diffraction gratings. Separate mirrors with their own sources of mechanical displacements are arranged for each grating. An electrooptic medium with semitransparent electrodes is placed between the outlet gratings and the common mirror. EFFECT: enhanced efficiency of the beam divider and expanded its functional abilities. 4 cl, 3 dwg
